Public lands managed by the Bureau of Land Management and Forest Service in the new National Monument are some of the most scenic and biologically diverse landscapes in northern California. They range from rolling, oak-studded hillsides to steep creek canyons and ridgelines with expansive views.

Surrounding the farms, ranches and orchards in a region stretching from Napa County to the mountains of the Mendocino National Forest north of Clear Lake, these lands provide valuable wildlife habitat, lands critical for scientific study and recreational opportunities for residents of the region and beyond.
